SASH-CHAIN FASTENE'R.

To all whom it may concern:

' Be it known that I, MICHAEL RAUGH'IlGAN, a citizen of the UnitedStates, and a resident of Norwich, in the county of New London and Stateof Connecticut, have invented certain new and useful Improvements inSash- Chain Fasteners, of which the following is a specification,reference being had to the accompanying drawings.

The object of this invention is to provide simple, strong and cheapmeans for attaching the weight-supporting chain to the window sash, andit is also my purpose to provide a form of fastener that may be readilyre-arranged upon the chain, if necessary, or desirable, in order tolengthen or shorten the chain connection.

My said invention is clearly illustrated in the annexed drawings, Figure1 being an outer face elevation of a fastening device embodying mypresent improvement and showing the chain properly connected there with.Fig. 2 is a side View of the same parts; the fastening device beingpartly broken away to disclose the means for supporting the end link ofthe chain. Fig. 3 is an outer face view of the said fastener, as itappears whenmade ready to receive the chain. Fig. 4 is a transversesectional view taken on the line 4-4: of Fig. 3, and Fig. 5 is a similarview taken on the line 55 of the said Fig. 3. Fig. 6 is a perspectiveView of the fastener as it appears before the tongues 1l12 have beenpartially folded down, as in Fig. 3. Fig. 7 is a perspective view of thefastener and chain, as they appear when assembled, and ready for use.

Referring to these drawings the numeral 10 indicates a semi-tubular bodyhaving its opposite edge portions formed with tongues 1l12 that areoffset from each other and are of such length that they (the tongues)may extend to the opposite edge of the body and find a seat in a notchor depression 13 in said body, as is perhaps best illustrated in Fig. 7of the annexed drawings. The said body portion is first swaged into theform illustrated in Fig. 6 and the tongues 11 and 12 are thentemporarily folded down as in Fig. 3; that is to say, so as to leavesufficient space between the end of the tongue and the body to allow achain link to he slipped over the end of the tongue, beforeSpecification of Letters Patent.

i said tongue is finally bent down into its cooperating notch 13.

The head of the fastener is formed i11- tegral with the described bodyand consists, as here shown, of a disk 14 having a struckup rim portion15 that is adapted to fit snugly in a corresponding depression in theedge of a sash, and the mid-portion of said disk is punched and bentinwardly, to provide a spur 16; the opening in said disk being of suchsize and shape that the first link of the chain may be inserted thereinand hooked over the said spur 16, as seen in Fig. 2 of the drawings.

I11 the operation of assembling the fastener and chain, the first linkis entered in the opening in the disk, and slipped over the spur 16, asI have just described. The chain is then swung to one side; that is tosay, out of alinement with the body 10, until the link that is adjacentto tongue 10 can be slipped over said tongue. The chain is thus swung tothe opposite side until the next link of the chain can be slipped overthe tongue 12, when the said chain is adjusted until it alines with thebody 10 and the tongues are then bent down into their respective notches18. When the parts are thus assembled they are so securely con nectedthat they cannot be separated by ordinary usage but, if it should bedesired to lengthen or shorten the chain it may be readily accomplishedby springing up the free end portions of the tongues 11 and 12 until thelinks may be removed from them, when the chainlinks may be re-arrangedon said tongues and upon the spurs 16. The tongues 11-12 are then bentdown into their respective notches and the device is again ready forservice. Importance is attached to the presence of the notches forwithout them I have found that the prongs are easily bent by the suddenjerks brought upon them as the window is raised or lowered quickly; butwith the prongs engaged in these notches it is practically impossible todislodge the prongs or bend them even though the window be thrown up ordown very suddenly.

I do not intend, or wish, in this application for a patent to claimbroadly the use of the rim-portions 14, as I have prepared anotherapplication for a patent in which I have illustrated, described andclaimed that feature of novelty with more particularity.

What I claim to be new and Wish now to ing provided With an inclinedspur extendsecure by Letters Patent is ing Within the same to engage alink of the 10 As an improved article of manufacture, a chain. sashchain fastener comprising a head por- 5 tion adapted to engage a sashand a body MICHAEL RAUGHTIGAN' portion extending therefrom and i formedWitnesses: With alternately oppositely disposed c0- FRANK C.
